Here's a report generated by "WhatIsHang", 10 minutes into a flight from PANC to KSEA. I had AS2012, FSinn, Vatsim, Ultimate Terrain X running, and was using the PMDG 777, as I usually do. I was using an average of 2.5 gigs of the available VAS limit of 4 gigs, and had VC frame rates of 50fps. The CPU and GPU were both running no higher than 50% on average and there was no CPU temp problem. 

     Recently, I completed an 11+ hour flight from KDEN to RJAA using all the same parameters and programs, with no freezes at all. I have the UI Automation core, and highmemfix installed.

     Can someone interpret the report below and give me an idea what the problem is? Thanks!

 I have the UI Automation core, and highmemfix installed

 

Which version of UIAutomationCore? You should test version other then you have now, and see of problem persist. Restart PC every time after replacing UIAutomationCore to see effects. And don't try to put UIAutomationCore anywhere else then FSX main folder(where you have FSX.EXE), just drop it there. 

 From what i know, it could be related to UIAutomationCore, see this thread http://forum.avsim.net/topic/421820-wrong-version-of-uiautomationcoredll/

I'll try to find out more about WhatisHang reports, didn't used this before. But interesting that i have downloaded WhatisHang a couple of days ago, si i had intention to learn about it anyway

 

Links to different versions:

 

 

here you can find 6.0.5840.16386:

https://www.dropbox.com/s/adxsx0mxb6wztil/UIAutomationCore.rar

 

and 6.0.6001.1800 here http://downloads.precisionmanuals.com/file_library/UIAutomationCore.zip

 

It's seems that only one of them is good for each system, but you must test both and see which is for you.

 

I'm going to read about AppHang WhatIsHang...

It says that your settings are set too high and some external app/program function is taking up too much VAS causing your app to crash.  Do you have any photoscenery installed?  Photoscenery will bring down your computer faster than anything else.  Like I have been telling everyone, you need to disable any addon scenery that you will not be using during a flight as there is a lot of photoscenery built into just scenery (Orbx/FTX stuff is an example).  You will not be able to fly very long if your have FSX constantly trying to load scenery all over the world during your flight.

 

You could send this to some programmer at Nirosoft (as they suggest) and maybe they would be able to give you more info but I doubt he/she would be able to understand it completely.  You see, it is not going to tell you if and when you are running low on VAS.  AppHangs are simply too high settings and/or scenery loading that is taking up VAS.

 

Best regards,

Jim

I have a program that monitors the VAS limit in real time, and it NEVER comes close to the 4 gig. limit. I don't have any photoscenery installed and I only get freezes, not CTDs. I tried to disable the UTX scenery in areas that I'm not using, but if you disable one you disable them all, I checked. I really think this is a random anomaly that just rears it's ugly head every so often, for whatever reason. I installed the latest UIAutomation core fix exactly where it said to in the directions. If it was a true VAS problem, wouldn't this occur all the time, since I run FSX the with the same scenery settings and addons whenever I use it?

As I said, I ran an 11 hour flight a few days ago with no freeze problems. Must be gremlins.

Thanks!

if you have time, i'd like to test some theories  

 

Enable simconnect log like here(backup your original simconnect.ini becouse you will need to disable log after this): http://forum.simflight.com/topic/45074-fsx-help-logging-simconnect/   Don't forget to set your real patch to "modules" there.

 

Just run FSX once, load the flight, rune it a couple of seconds and close FSX. After FSX is closed completely, go to "modules" folder and copy "SimConnect0.Log" and  "FSUIPC4.log" and post them here, or atach to your post. They are probably most underestimated diagnostic tools for FSX.

 

 

I have fixed my freezing with 777 this way, i had some simconnect conflicts which makes EZDOK to freeze whole FSX. Errors will be in log, and we can fix that easily, if you have any. It's worth a shot

 

Reasons for freezings are many, i though that in your case may be uiautomationcore.dll, becouse of your WhatisHang report. Try this thing with simconnect and take a look at some of mine older post, those settings can realy add some stability to your FSX: 

 

http://forum.avsim.net/topic/407468-ctds-with-ezdok/#entry2664798

 

and

 

http://forum.avsim.net/topic/407468-ctds-with-ezdok/#entry2665090

 

From second link, you don't need to disable DEP if you don't want, and you don't need to go to simforums for windows 7 tuning. Better type in google "tweakhound" and tune windows 7 like there. I found huge difference in stability and performance. Great website! 

 

I hope some of this things will help you, there is allways some reason behind crashing and freezing which allways can be fixed, if you have enough time

You lost me in the first sentence. Thanks anyway.
